LocolvIoTlvE-QAB SEAT.

SPECIFICATION forming part of Letters Patent No. 766,981, dated August 9, 1904,

Application filed December 29, 1902.

To rif/L whom, t puny concern:

Be it known that I, BRADLEY W. ANDERSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Loeomotive-Cab Seats, of which the following is a speciiication.

My invention relates to improvements in yielding supports for locomotive-cab seats.

The object of my improvements is to provide an adjustable yielding support for locomotive-cab seats which shall be simple in construction, durable and eflicient in use, which may be obtained at slight cost and owned by the engineer or his fireman and readily attached by either to the leg of his cab-seat on taking their engine, which may be as readily adjusted for use or detached at the end of the run and taken home or put away with their other eil'ects ready Jfor use on the next engine taken out, and which will relieve the engineer or his iireman of the jar and vibration of the engine, which when longcontinucd often produce disease, compelling cessation of work and in some cases permanent retirement from service.

With these and other objects in view the invention consists of the features shown and described, all of which may be understood by reference to the accompanying drawings, in which-M Figure 1 is a side view of thelocomotive-cab seat with my invention applied thereto, the

latter being shown in section; Fig. 2, a view` p in elevation of my invention detached from the seat; Figs. 3 and 4:, top plan views, respectively, of an upper and lower collar employed in my invention; and Fig. 5, a view in'elevation of a rivet employed in my invention.

Referring to the drawings in detail, A represents the wall of a locomotive-cab; B, the lloor of same; C, a seat which is provided with a cushion D, has one edge hinged to the cabwall by means of the hinges E, and has secured to its under side and near its outer edge a cleat F, to which is hinged the leg G, which is adapted to have its lower end rest on the licor of the cab. The parts thus far enumerated are of the character in general use on Serial No. 137,060. (No model.)

railroad-locomotives and form no part of my `invention proper, which latter consists oi' the sleeve K, which is adapted to receive the said leg, the spiral spring J surroundingsaid sleeve and having at each end aportion 7" extending parallel with the sleeve, and the upper and lower collars H and I, respectively, the former of which has an annular iiange if, provided with two o penings 7b3, in one of which is secured the upper end oi' the spiral spring and in the other of which is secured the rivet N, provided with an eye a, in which a coil of the spring is secured, said upper collar having also a countersink h5, a central opening it to receive said leg, and a boss l, through which and the collar is fornied a threaded opening Y to receive the thumb-screw L, the said lower collar having' an annular flange 2, provided with two openings 3, in one of which is secured the lower end of the spiral spring' and in the other of which is secured the rivet N, provided with an eye a', in which a coil oi' the spring is secured, said lower collar having also a central opening fr," to receive said sleeve and a boss fil", through which and the collar is formed a thread-opening to receive the setscrew M.

My invention is applied to a locomotive-cab seat of the style shown and described by passing the leg oil'I same through the central opening in the upper collar into the said sleeve and' is secured to the leg by means of the thumbscrew in the upper collar.

It will be seen that the application of my invention to the leg of the seat will have the effect to elevate the outer edge ol the latter. This feature, however, is considered more of an advantage than a disadvantage, since it will prevent the engineer from sliding' there-from.

The relative position of the outer edge of the seat is regulated by adjusting the lower collar, which is adapted to be removably secured to the sleeve by means of the set-screw in said lower collar.

The opening through the sleeve and the opening through the spiral spring are of suitable size to permit the leg and the spring' to move up or down freely, thereby counteracting the Jar and vibration oil the engine.

end resting on the Hoor, a Collar adjustably and removably secured to the sleeve, and a spiral spring surrounding the sleeve and having its ends connected with said Collars respeotively.

In testimony whereof I afx my signature in presence of two witnesses. Y
